Question

What is the meaning of "this is the deal"?
Example:

Listen boys. This is the deal.

Answer

1) the first meaning is "agreement" and everything close to it (proposition, plan we have agreed on) and is usually followed by the description of what is going to happen.

2) The second meaning has nothing to do with "agreement" and this phrase is simply used to describe a situation or what is happining.  ( i think it helped u)
